Java Character.equals()用法及代码示例


java.lang.Character.equals()是Java中的一个函数,用于将该对象与指定对象进行比较。如果参数不为null,则结果为true,并且是一个Character对象,表示与此对象相同的char值。

用法:

public boolean equals(Object obj)

参数:该函数接受单个参数obj,该参数指定要与之进行比较的对象。


返回值:该函数返回一个布尔值。如果对象相同,则返回true,否则返回false。

以下示例程序旨在说明上述方法:

示例1:

// Java program to demonstrate the function 
// Character.equals() when two objects are same 
import java.lang.*; 
  
public class gfg { 
  
    public static void main(String[] args) 
    { 
  
        // assign values to c1, c2 
        Character c1 = new Character('Z'); 
        Character c2 = new Character('Z'); 
  
        // assign the result of equals method on c1, c2 to res 
        boolean res = c1.equals(c2); 
  
        // print res value 
        System.out.println(c1 + " and " + c2 + " are equal is " + res); 
    } 
}
输出:
Z and Z are equal is true

示例2:

// Java program to demonstrate function 
// when two objects are different 
  
import java.lang.*; 
  
public class gfg { 
  
    public static void main(String[] args) 
    { 
  
        // assign values to c1, c2 
        Character c1 = new Character('a'); 
        Character c2 = new Character('A'); 
  
        // assign the result of equals 
        // method on c1, c2 to res 
        boolean res = c1.equals(c2); 
  
        // prints the res value 
        System.out.println(c1 + " and " + c2 + " are equal is " + res); 
    } 
}
输出:
a and A are equal is false
